Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,0

Sphinxa [80]

Answer:

$Sea\ Level = 0\ ft$

The farthest point is the Challenger Deep

Step-by-step explanation:

Given

$Highest = +29029ft$

$Least = -35,797ft$

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

$Sea\ Level = 0\ ft$

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

$Highest = +29029ft$ to $Least = -35,797ft$

-35,797 ft has the highest magnitude.

Hence:

The farthest point is the Challenger Deep

over the weekend, Brady and Jake drove to Key West go scuba diving. Now they're preparing to go home.Brady needs gas for his jee

velikii [3]

His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.

He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal

He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal

With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles

How do you do this equation

RUDIKE [14]

When you solve, a quadratic formula is set up as ax^2+bx+c so in this scenario a is 1, b is -1 and c is -6.
-(-1)+- √- 1^2-4(1)(-1)/2(1) is
1+/-√1+4/2 equals -2 and 3 making the answer c

Bezzdna [24]

Answer:

Part A) The amplitude = 24

Part B) The period = 24

Part C) Vertical shift = 36

Step-by-step explanation:

The general equation of the sine function:

y = A sin (Bx) + C

Where A is the amplitude and B = 360°/Period and C is the vertical shift

See the attached figure which represents the graph of m and f(m)

So,

Part A:

The function has minimum at 12 and maximum at 60

The difference is = 60 - 12 = 48

So, The amplitude = 48/2 = 24

Part B:

Period: The period of a periodic function is the interval on which the cycle of the graph that's repeated in both directions lies.

We can deduce that the function completes one cycle within 24 months

So, the period = 24

Part C:

Vertical shift is obtained at m = 0

So, f(m) = 36

36 = A sin (0) + C

C = 36 ⇒ Vertical shift

So, The amplitude = 24

The period = 24

Vertical shift = 36
